SPECIFICATION forming part of- Letters Patent No. 629,172, dated July18, 1899,

Application filed May 2'7, 1899. Serial No. 718,421* (No model.)

rTo all whom t may concern:

Be it known thatI, HUIE M. RASLE-Y, a citizen of the United States ofAmerica, residing at Letts, in the county of Louisa and State of Iowa,have invented certain new and useful Improvements in AntirattlingThill-Couplin gs, of which the following is a specification,

reference being had therein to the accompanying drawings.

This invention relates to antirattler attach.

vsame time comparatively inexpensive.

With the above and other objects in view the invention consists in thedetails of construction and in the arrangement and combination of partsto behereinafter morefully set forth and specifically claimed.

In describing the invention in detail reference will be hadv to theaccompanying drawings, formin g part of this specification,- whereinlike characters denote corresponding parts in the several views, and inwhich-A Figure l is a side viewof a thill-coupling attached to 'avehicle-axle with the invention attached. Fig. 2 is a plan view lookingat the bottom of Fig. 2. Fig. 3 is a perspective view illustratingcertain elements of the invention detached.

In the drawings, l indicates the` axle, 2 the clip, and 3 lugs of theclip that embrace-the ends of the thilllsocket, all of which being of.usual and well-known construction will not be described in detail'.

In connection with the thill and the apertured lugs it is my purpose toemploy a bolt,

et, having neither head nor threads, but having an annular groove 5 ateach end. The bolts 4 are 'of such length as to project from each sideof the lugs, and the grooves are so positioned as to lie j ust outsidethe walls of said lugs. The thill-iron 6 has the usual socket oraperture to receive the bolt.V

The antirattling device comprises a spring bent centrally with a loopedportionr 8 and parallel legs 9. Each leg is coiled around a yoke' l0near its ends, and the extremities 1l of the legs are bent up and curvedto approximate the contour of the outer surface of the thill-sockets,which they engage. The yoke has ends extending diagonally upward, witheyes lla formed by curving the said ends, and the eyesso formed receivethe ends of the bolts which -protrudeth'rough the lugs 'of the clip. Thewire forming the eyes of the ends of the yoke is partially embedded inthe annular grooves, and as the spring exerts a downward pull on theyoke the ends are held in the grooves, and as the grooves, as described,are close to the walls ofthe lugs the purpose is to have the loopsforming the eyes of the yoke engage the sides of the lugs to furtherretain the parts in proper' position. Itwill be noted, too, that thetension of the spring presses the thill into firm engagement withthe'bolt and the bolt is held securely in the lugs. Hence the parts arenot free to move or make a noise.

As a means for regulating the tension of the spring a loop l2 isarranged over the clipplate 13 and has its ends 14 attached to the legsof the spring by being coiled therearound.

'When the loop is applied, the tension of the spring maybe variedaccording to the length p kof the loop, and should the spring becomeWeak a shorter loop may be readily applied without theexercise of undueskill.

The construction, operation, and advantages will, it is thought, heunderstood from the,foregoingdescription, and-it will be noted.

IOO

around the legs of the spring, as and for the ro purpose described.

In testimony whereof I affix Iny signature in the presence of twowitnesses.
